Issue with aapt.exe

I'm using the latest version of the ADT Bundle downloaded on the android developers site. I'm on Windows 7. My R.java file is not compiling correctly due to the fact that I get the following crash message from Windows:

Here is the problem details output:

Now because of this, my R.java file keeps disappearing and the following problems show up:

Take note of the first problem on that list

Now I've went through the following steps about 10 times:

1. Uncheck build automatically
2. Clean project,
3. Check build config
4. Rebuild project

If your going to say to do any of this as a solution then don't post a solution because I'm not going to do something I've already done a billion times.

I ported this project over from Android Studio from all its errors and, in my experience with Eclipse, I've never seen this aapt.exe error. What is aapt.exe and what's its purpose?

Any help is greatly appreciated.
